ERIC negotiates an arena

Watch multiple ERICs negotiate a complex arena in this video, which is part of the free online course, Begin Robotics, by the University of Reading.
Here we have ERIC using its infrared sensors for detecting how far the wall is, and it’s moving around accordingly. Moves there towards the wall, and then it rocks far too much, and turns itself off. But we then use the microphone to get it going again. [WHISTLE] You can whistle at of your ERICs. Here we go, in the open. Moves towards the walls, sees the wall, turns away from it. Moves again, sees the wall, turns away from it. Whoops. Head banging ERIC. Here we have ERIC with some obstacles to avoid, as well as the wall. Will he go between the obstacles? Yes. Well done, ERIC. And forward. Just about avoided it. And again. This time, can it go behind? Yes.
Well done.
And now we have three ERICs, each programmed the same way. We’ve made the arena a little bit more sophisticated, with a triangular shape there, but the robots are able to move around, navigating, avoiding the triangle. [WHISTLE]
There is now a hole in the arena. Will someone escape?
We have one over here. Is it going to see the gap? [WHISTLE]
And we have an escapee!

Watch ERIC (and his friends ERIC and ERIC) navigate around an increasingly complex arena, demonstrating sensors in action.
